.SH DESCRIPTION
|
|
.I Gtf
|
|
is a utility for calculating VESA GTF modes. Given the desired
|
|
horizontal and vertical resolutions and refresh rate (in Hz), the parameters
|
|
for a matching VESA GTF mode are printed out. Two output formats are
|
|
supported: mode lines suitable for the __xservername__
|
|
.B __xconfigfile__(__filemansuffix__)
|
|
file, and mode parameters suitable for the Linux
|
|
.B fbset(8)
|
|
utility.
|
|
|
|
.SH OPTIONS
|
|
.TP 8
|
|
.BR \-v | \-\-verbose
|
|
Enable verbose printouts This shows a trace for each step of the
|
|
computation.
|
|
.TP 8
|
|
.BR \-x | \-\-xorgmode
|
|
Print the mode parameters as __xservername__-style mode lines. This is the
|
|
default format.
|
|
.TP 8
|
|
.BR \-f | \-\-fbset
|
|
Print the mode parameters in a format suitable for
|
|
.BR fbset(8) .
